I have a bunch of wool that needs lanolizing and I have never done it before. I have some sudz n dudz lanolin to use and I read up on how to do it so I think I'm good there. I just have one question. Can I use the same lanolin water to lanolize more than one wool item? Or do I have to change the water or add more lanolin each time? I have 4 longies and 3 soakers to do.
